The number of SUV models getting at least 25 miles per gallon (mpg) has doubled in the last five years, while the number of cars achieving at least 40 mpg has increased sevenfold. Research shows that new policies can drive efficient vehicle use even further, lowering emissions and saving consumers money.

The U.S. EPA has proposed standards to limit power sector emissions, which, once adopted, are expected to reduce carbon pollution from power plants by 25 percent by 2020. But as we recently noted in our public comment on the proposal, increasingly cost-effective efficiency and renewable energy opportunities mean that the EPA can and should require even greater emissions reductions.

At COP 20 in Lima, country representatives are coming together to discuss plans to reign in global greenhouse gas emissions.

A new interactive from WRI reveals the history of carbon dioxide (CO2) emissions, as well as what needs to happen to stay within world’s “carbon budget” and prevent the most disastrous impacts of climate change.

With China at an economic and environmental crossroad, ongoing cooperation on climate and clean energy with the U.S. can yield significant social and economic rewards for both countries. The benefits of this course can and must go together to tackle climate change and create vibrant economies for the 21st century.

The Greenhouse Gas (GHG) Protocol’s Mitigation Goal Standard, launched today, provides the first-ever standardized approach for designing, assessing, and reporting progress on a variety of national and subnational mitigation goals. The standard can help governments set emissions-reduction targets, meet domestic and international emissions reporting obligations to groups like the UNFCCC, and ensure that efforts to reduce emissions are actually achieving their intended results.

Tunisia launched its renewable energy program in 2010 to scale up solar photovoltaic systems and used the Greenhouse Gas (GHG) Protocol’s Policy and Action Standard—to find out just how much the program would reduce the country’s greenhouse gas emissions.
